TV-B-Gone-zilla! Rawr!

tv-zilla

TV-B-Gone: antisocial nuisance or harmless prank? Whatever your feelings, there’s no denying this device has become a staple of the DIY hacking crowd, as evidenced by the countless derivatives since hatched. This latest mutation crushes them all.

[manekinen] from the Polish electronics blog Elektroda (“Electrode”) wasn’t satisfied with high-power TV-B-Gone designs using multiple 5mm infrared LEDs, so he created his own using a single one-Watt monster. The device is concealed in an ordinary flashlight casing, making it somewhat inconspicuous. A custom PCB containing an ultra-minimalist version of the TV-B-Gone circuitry sits just behind the reflector. The choice of reflectors determined maximum distance vs. coverage…they opted for distance. Specific figures aren’t given, but we estimate this thing could shut off televisions on Mars.

The original article (Polish or Google-ized English) includes construction photos and an archive (.rar) of project files including Eagle schematics and C source code.

Would it be totally irresponsible to mention there’s now a 3-Watt version of this LED? We’re just sayin’.

    Now we just need one that utilizes an infrared laser and rifle scope.

    lol Good stuff. Let’s see them build one into a spot light housing.

    This looks good but who seriously wouldn’t look weird taking a flashlight into a store and pointing it around.

  4. Doug says:

    @patrick

    Certainly not the guy who is standing across the street from the store turning off the TV’s from the outside.
    Long distance is the key here.

    What I don’t understand is the button. Most flashlights like this have a click on, click off type button. Not a momentary switch which is what the description seemed to imply (in the Google-ized English at least).

    @patrick: CSIs

    A little smaller and you could fit it in a key chain flashlight. And there are those LED key chains already that might provide a good case for something like this. The coin cell batteries those hold might be a bit weak though.

    @Doug

    The article says the code stops after sending all the codes. So even though it isnt using a momentary switch it seems they did think around that.

    “When you turn on “Torch” to the circuit current flows, and uC in turn sends all the codes, and at the end goes into power-down mode”

  8. We should take this to the next level… install this on a bicycle headlamp and drive around a dense city.

    Electric company: Woah, did a transformer just explode? What’s up with the sudden drop in power consumption?

    WIN JUST WIN. ANd @Dating for Geeks that would be a PERFECT idead :D

    Someone use the 3-Watt and take it to Times Square. I always wondered if there were remotes for those giant TVs.

    Hi, someone has sent this to hackaday, with wrong link and wrong informations…

    I am author of this project, please go to my website for short english description http://diy.elektroda.eu/?p=514

    @patrick – there is an original switch on/switch off button, no need to use pushbutton. Just switch on, and uC will start to send commands. You can switch off in any time, when tvs are disabled, or, if you not, it will stop sending automatically as original. Difference is, in original from ladyada uC is powered all time and you just reset it with pushbutton.

    I love TV be gone and in the tv shop its funny. But i work in the AV industry. Some of you think its funny to stop a presentation or demonstration. Its ok.:) Just don’t get upset when an AV technician beats you down in public, you are a punk bitch after all. (we are older than you,, and are FORCED to deal with macs on a regular basis.)

    “this device has become a staple of the DIY hacking crowd”

    What other kind of hacking crowd is there?

  14. Nick says:

    I have one but never had the balls to use it. It seems pretty rude / passive-aggressive. If there’s some place that always has a TV on and you don’t like it, why not just go somewhere else?

  15. Nick says:

    @Big J, I’m also involved in the AV industry (part time, but not full time), and always have put a bit of lx tape over the reciever of the plasma’s, just to ensure this never happens. Haven’t bothered with the projectors, beign able to turn them on / off remotely is a great help when they are in the truss. Which makes me wonder, does a TV-B-Gone work on projectors.

  16. IBeHoey says:

    Yeah.. $80+ dollars for a single LED is pretty steep. I would love to see some numbers on the range you get with this though. Until then, Ill just stick with my 300ft range EHP.

  17. IBeHoey says:

    @Nick

    If the projectors use infrared remotes to shut them off, then yes, all you would need to do is capture the power off codes. To capture, you can modify a mini-pov kit (or build your own) to capture the codes via the serial port on your PC.

    3w, but I swapped the transistor with a tip120 darlington.

  19. amk says:

    This looks great for long range applications. I’d like to see a tv-b-gone embedded in something less conspicuous, like a cellphone, for close range. You could take your time aiming a cellphone and pretending to be texting, I doubt anyone would notice. Hmm.

  20. Scott says:

    @Doug

    Modern “tactical” flash lights have momentary buttons where a partial push is momentary and a full click in turns on/off. See Surefire etc. for reference.

  21. Doug says:

    Well the shape of this one should be less painful, as compared to the rectangular shaped case item, as that giant you pissed off proceeds to shove it where the Sun doesn’t normally shine for most of us.

  22. Haku says:

    Put the LED in the palm of your hand like the rocket/blaster Iron Man has, then you can pretend to be him and zap tvs off, or something… ;)

  23. cgmark says:

    The way to kill any attempt at someone using this and still changing your channel by remote when you want is to use a jammer. A 555 timer ic + IR LED set for 36Khz and 44Khz will stop any remote control in the room from working. Then when you want to change the channel you switch it off. Great for places like bars that have tv up high.

  24. sl says:

    On DealExtreme you can get all kinds of these multi-watt LED flashlights for around $20. Most of them have replaceable multi-chip LED emitters and drivers. Then you’ve got the lenses and the housing and so on.

  25. Will says:

    tv-b-gone again? maybe someone can build one with an arduino and twitter feed and make the ultimate hackaday hack.

  26. Manekinen says:

    Guys, remember, you need a 940nm IR, not 850! 850 will strongly decrease distance!

  27. EJZ says:

    This is great. Going even more stealthy is the next level of progression. Hacking the ball caps that are coming out with leds in the bill is next!

  28. Andy says:

    Be careful with these high power IR LEDs. > 1 W from a point source, and no eyelid reflex to protect you, that’s enough to cause some damage.

  29. PSN Coder says:

    Haha very nice, but can be dangerous!

  30. FreePSNCards says:

    that looks tight :o
